What it is

The Worcester Bosch 87161131600 is a single wiring harness with green/yellow sheathing, supplied by Worcester Bosch as a spare electrical component for the Greenstar Heatslave External range of oil-fired condensing boilers. It forms part of the appliance's internal wiring, carrying a single circuit between the boiler's electrical components. The green/yellow sheath follows the standard UK colour coding used to identify earth conductors.

Signs this part needs replacing

  • Visible damage to the sheath, such as cuts, chafing or heat marking
  • Exposed, oxidised or corroded conductor ends at the terminal
  • Intermittent electrical faults traced to the harness rather than the connected component
  • Loose, pulled or poorly secured harness connections

Before you order

  • Confirm the boiler model against the fit list above
  • Check the part number marked on the existing harness or the appliance's documentation
  • Inspect the existing lead to confirm that a single-conductor green/yellow harness is the correct item for the connection being replaced
